摘　　要：由于高速铁路列车运行速度较高,对隧道安全使用功能要求也相应提高。严寒地区高铁隧道的渗漏水、挂冰等病害,一直是困扰东北铁路运营部门的难题。防止全包防水型隧道后期渗漏水是目前铁路隧道建设的重点研究内容。介绍哈牡客专爱民隧道全包防水设计系统,并总结分析隧道运营后的实施效果,可为严寒地区高铁隧道的防寒保温及全包防水设计提供参考。Due to the high running speed of HSR trains,the requirements for the safe service of tunnels are correspondingly improved.Water leakage,ice hanging and other diseases of HSR tunnels in the severe cold regions have always been the problems that puzzle railway operation departments in Northeast China.In case of water leakage of the fully-enclosed waterproof tunnel put into operation for a long time,it is difficult to find an effective solution for elimination,which is also the key research subject of railway tunnel construction at present.This paper introduces the fully-enclosed waterproof design system of Aimin Tunnel of Harbin-Mudanjiang Passenger Dedicated Line,and summarizes and analyzes the implementation effect after the tunnel is put into operation,which provides a reference for the cold protection and thermal insulation as well as the fully-enclosed waterproof design of HSR tunnels in severe cold regions.
